Five people were injured in the holiday weekend crash that killed Ashton Sweet, a 14-year-old cheerleader at Northwood High School. She suffered an irreversible brain injury.

Sweet had been kept alive on a breathing machine so her organs could be evaluated for donation. She was declared dead at 1 p.m. Tuesday, according to the Orange County Coroner's Office. Ashton's parents had made the determination to allow for organ donation, police officials said.

Krista Merassa, 15, was reported in critical condition.

"This is just devastating," said Ian Hanigan, spokesman for the Irvine Unified School District. "There is nothing worse that our school community can go through than to lose somebody so young. Our thoughts and our prayers are with Ashton's family, as well as with all of those who were in the car."

On Tuesday morning, several students at Northwood High School were seen wearing white, walking past news vans and reporters on their way to class.

Austin Jeffrey Farley was taken into custody after the Sunday morning crash on suspicion of driving under the influence. According to online arrest records, he is being held in lieu of $1 million bail.

No formal charges have been filed against the 26-year-old driver. The investigation is open and the District Attorney's Office does not have all the evidence so a decision has not been made on filing charges, Chief of Staff Susan Kang Schroeder said.

Farley has had several run-ins with the law, including previous DUI arrests, according to court records.

Farley was arrested by the California Highway Patrol on May 4, 2004. Then 19, he was charged with being a minor with a blood-alcohol content of .05 percent or more, court records show. That charge was dismissed in June 2004 after he was sentenced to a diversion program.

In July 2004, Farley was back in court, charged with having a license suspended after allegedly refusing to submit to a chemical test. Farley pleaded guilty to the charge and was sentenced to three years' probation and $300 in fines.

In February 2009, he was pulled over by authorities again. He was charged with driving under the influence, disobeying a court order, battery on a peace officer and driving with a suspended license. He pleaded guilty to the charges and was sentenced to three years of probation, 104 hours of service in lieu of fines, 30 days in jail and six months in a first-offender alcohol program. He was also required to attend a victims panel for Mothers Against Drunk Driving.

Friends and family said the four girls were out celebrating a friend's birthday Saturday night and were being driven home by the father of one of the girls when the crash occurred about 1 a.m. Sunday.

Michael Ghaemi, 48, was driving the girls in an E-Class Mercedes-Benz on Culver Drive. He said he was passing through Irvine Boulevard when they were struck by a pickup on the left-rear side of the car.

On Sunday night, friends and family of the girls gathered at the site of the crash, lighting candles, bringing flowers and leaving notes for Ashton.

"We are doing our best to support the kids," Hanigan said.

Five counselors were expected to be available on campus Tuesday, reaching out to friends and classmates of the teenage girls injured in the crash.

Ashton was a cheerleader and in track-and-field, Hanigan said. She was also involved in the high school's "Wolfpack" club, which pairs special-needs students with other students for school activities.
